WebHill cipher is one of the techniques to convert a plain text into ciphertext and vice versa. There are two parts in the Hill cipher – Encryption and Decryption. Encryption – Plain text … WebTo encrypt a message using the Hill Cipher we must first turn our keyword into a key matrix (a 2 x 2 matrix for working with digraphs, a 3 x 3 matrix for working with trigraphs, etc). We also turn the plaintext into digraphs (or trigraphs) and each of these into a column vector.
